2008 Mercedes-Benz CLC 2.1L Diesel · KM58 BNX

Based on the DVSA MOT records supplied, this 2008 Mercedes-Benz CLC presents a maintenance trend that is clearly worsening. The most recent test on 19 November 2025 at 68,669 miles passed, but the tester flagged multiple advisories that point to deteriorating underbody condition. Both rear brake pipes were noted as corroded and contaminated with grease or other material, all rear suspension components showed corrosion, and both front wheel bearings had slight play. These are not new isolated faults. They represent a progressive decline from a clean bill of health in 2022 and 2023, and the pattern suggests corrosion and component wear are accelerating as the vehicle ages. The mileage profile tells a specific story. Between 2022 and 2024, the car covered roughly 8,900 miles in two years, which is modest but consistent with regular use. However, the jump from 62,328 miles in November 2024 to 68,669 miles by November 2025 represents 6,341 miles in a single year, a notable increase in annual usage. This is still low for an eighteen-year-old vehicle, averaging about 3,815 miles per year overall. The lower mileage likely helped preserve the drivetrain and interior, but it does not protect the chassis and suspension from age-related corrosion, which is exactly what the recent tests reveal. A buyer inspecting this CLC in person should focus on the rear underside. The recurring corrosion across all rear suspension components, combined with corroded rear brake pipes, raises legitimate concerns about structural integrity and braking system reliability. Surface rust on suspension arms and subframes is common on older vehicles, but the tester flagged it consistently enough to warrant a close visual check for pitting, flaking, or weakened mounting points. The rear brake pipes deserve particular attention, especially where they are covered in grease or other material, as this can trap moisture and accelerate internal corrosion that is not visible externally. The front wheel bearings also merit investigation. Slight play was recorded in both the November 2024 and November 2025 tests, indicating a slow but persistent wear progression. A raised-wheel check for roughness or excessive movement would confirm whether replacement is imminent. Tyre wear patterns should also be examined, given the November 2024 advisory for both rear tyres worn close to legal limits and worn on edge, which suggests possible alignment issues or neglected rotation. Overall, this car appears mechanically sound for its age and mileage, but the corrosion trend in the rear suspension and braking system is the dominant concern and should be the priority of any pre-purchase inspection.
